by base and lateral side

Definition:

The Isosceles triangle is a variety of scalene triangle, which has two congruent sides (equal). The third side is called base.

The area of an isosceles triangle by base and lateral side, is determined by a modified version of the formula for right triangle – half product of the base and its height, deducted by one of congruent sides as hypotenuse.

Computing relationship:

unde:

a — the lateral side of the triangle;

b — the base of triangle;
